They don't really have an incentive to spell it out, in detail. I did a quick patent search, but didn't find anything obvious.

Here's a QD-OLED explainer, I found.

It goes into lots of details that aren't necessarily relevant to QD-OLED, but there's a part near the end which could reveal some of the challenges:
Having your (OLED) cake and eating it, too
Blue OLED material — the light source of QD-OLED displays — is a notoriously tricky substance to work with.​
Much like other OLED materials, there’s a three-way trade-off between lifespan, brightness, and efficiency. Generally speaking, any time you prioritize one of these attributes, the other two suffer. Drive an OLED pixel hard enough to produce the brightness you want and you not only diminish its life expectancy but also its efficiency.​
But QD-OLED displays may prove to be the exception to this rule. By using three layers of blue OLED material per pixel, each layer can share the brightness burden.​

My guess is that it might have something to do with how to balance the distribute current between the layers, and/or things like balancing overdrive vs. panel life, etc.
So that mean that QD-OLEDs have longer lifespans? I'm a bit confused on the whole QD-OLED thing. from what I've heard, all the QD part of a QD OLED is just a color filter (that could easily be wrong) My question is whether QD-OLEDs have the perfect blacks of normal OLEDs.

As far as the blacks go, yes they do, and no they dont. From the reviews I have seen in a very dark room the blacks seem a little more than black, but that is just from what I have seen. No idea why that is a thing vs W-OLEDs.

That article claims QD-OLED is efficient, because it's a purely emissive technology. In other words, it has no subtractive filtering that could bleed light.

There could be other reasons it might not have perfect blacks, however. Being purely emissive does seem like a good start.

Here is how a QD is layered compared to a normal LCD;
